UN welcomes reports 'deal reached' on Homs

The United Nations welcomed reports that an agreement has been reached to allow the evacuation of civilians from the besieged Syrian city of Homs and for aid to be delivered, a UN spokesman said. The rebel-held Old Homs districts in the centre of the city have been under tight siege from President Bashar al-Assad's troops since June 2012. Thousands of residents there live in dire conditions, amid an acute shortage of food and medicine. Al Jazeera's James Bays reports from Washington DC.
